HP / Agilent 66111A Fast Transient dc Source, 15V, 3A

The HP/Agilent 66111A Fast Transient DC Source delivers 15V at 3A with engineered fast transient response for dynamic test environments. Built on HP Fast Response Power Technology, this unit minimizes voltage sag during load transients and rapidly settles output changes—critical for mobile phone testing, battery charger validation, and semiconductor characterization. Peak sourcing reaches 5A with 2.8A sink capability, supporting both forward and reverse power flows. Low output noise and automatic sense-wire detection prevent measurement errors and calibration faults. GPIB control with SCPI command support and remote voltage sensing enable fast, accurate testing in high-throughput manufacturing and lab environments.
